EXPANDABLE AND CONTRACTIBLE AUXILIARY WINDOW FRAMING Ernest Camerino, Lindenhurst, N. Y.

Application September 21, 1954, Serial No. 457,341

1 Claim. (Cl. 20-55) This invention pertains to new and useful improvements in auxiliary window units, and it is particularly concerned with improvements in the framing thereof.

A general object of the invention is to provide auxiliary window framing that is expandable and contractible, whereby an auxiliary window unit may be fitted to different size window frame openings.

Auxiliary window units embodying the invention are obviously of definite advantage to the installer, for he no longer vwill be required to carry large stocks of auxiliary windows to accommodate odd and standard size window-openings. Storm windows embodying the present invention may be fitted to window openings of various sizes. Under such circumstances, odd size units need not be carried in stock. Standard sizes may be expanded or contracted, because of the novel framing of the invention, so that they may be used in odd size window openings. y This advantage also accrues to the householder having odd size window openings, for he can now be accommodated through use of the invention with expanded or contracted standard sizes at no added expense.

A further object of the invention is to provide expansion framing for auxiliary window units, which will prevent distortion in the framing arising from weather conditions, settling of the building, and other causes.

A still further object of the invention is to reduce to a minimum the different sizes of auxiliary window units that an installer must carry on hand to accommodate various size windows.

The foregoing objects and advantages of this invention as well as others will appear more fully hereinafter from a consideration of the detailed description which follows taken together with the accompanying drawings wherein an embodiment of the invention is illustrated. It is to be expressly understood, however, that the drawings are for purposes of illustration and description, and are not to be construed as defining the limits of the invention.

In the drawings:

Fig. 1 is a front elevational view of an auxiliary window unit embodying the invention;

Fig. 2 is a cross section thereof; and

Fig. 3 is a rear view of a corner detail.

In the drawings there is disclosed an auxiliary window unit including a rectangular frame or casing 1, the walls 2 of which extend from front to rear and are of sufricient depth to accommodate conventional sash tracks and sash members 3, shown in broken line. The casing is provided with the usual inwardly extending retaining lip 4 about the forward edges of its walls.

Projecting out at right angles from the rear edges of the four walls of the casing is a continuous flange 5. The latter provides the back wall of a continuous shallow channel 6 about the casing. The channel opens out rearwardly and is inwardly lipped as at 7. The four Walls of the casing, originally separate, are united together in rectangular form by suitable means, such as flat rightangled members 8 secured in the corners of channel 7.

Projecting from the outer side faces of the four walls of the casing and in parallel spaced relation to flange 5 is a second continuous ange 9. In a narrow continuous channel 11 formed about the casing between flanges 5 and 9 is received the inner marginal portions of a at rec* tangular frame member 12.

Frame 12 serves to support the auxiliary window as a unit to the framing of a window opening. To this end, the two pairs of strips 14 and 15 of frame 12 are provided with a plurality of holes to accommodate suitable fasteners 20. The auxiliary window unit is secured in a window opening by fastening the frame 12, preferably to the window stops 17 as in Fig. 2, though, as will later appear, frame 12 may also be secured to the outside frame 10 of the Window opening.

The perimetrical channel 11 formed between flanges 5 and 9 is of suicient depth to receive a substantial portion of the strip members 14 and 15 that comprise frame 12. However, the strip members are preferably not received to the full depth of the channel, but normally project only part way therein. By this arrangement, it is clear that a standard size auxiliary window unit may be maintained to fit a particular size window opening. Where a window opening of an odd size is encountered, either' smaller or larger than the nearest standard size, the strips forming frame 12 may be adjusted to properly fit the window opening. They may be pressed further in the channel or drawn further out of the channel, as may be required to increase or decrease the overall size of the auxiliary window unit.

It is clear that the strips 14 and 15 of frame 12 could not be pressed further into the channel without interfering with one another, and to avoid this an opposed pair of the strips, here strips 14, are notched at the inner ends thereof, and the marginal ends of strips 15 are offset to overlap the end pieces 16 of strips 14.

A tight and floating fit of frame 12 in the channel 11 is provided by a suitable resilient lining 18, preferably of rubber, desirably contained in the channel.

While the strips forming frame 12 may be unconnected from one another at the corners, it is desirable that the overlapping corners of frame 12 be normally connected to one another by a readily removable rivet 19. In this construction, auxiliary window units having an overall standard size adapted to fit window openings of standard size may be held in stock. In the event an odd size window opening is encountered, the rivets 19 may be readily removed so as to allow the strips of frame 12 to be adjusted further in or out of channel 11 as may be required. The adjusted size may then be installed in the window opening.

The oval holes in which the rivets 19 engage allow limited adjustment of the strips of frame 12 without removing the rivets.

The auxiliary window unit is preferably fitted in a window opening wherein the frame 12 is limited against and fastened to the customary window stops 17, as in Fig. 2. This is called inside installation. In some cases it is desirable to secure the frame 12 to the outside framing 10 of the window opening. This is called outside installation. In either case, it is clear that frame 12 may be adjusted by extending or retracting its members to fit the window opening.

The rivets 19, securing the strips of frame 12 to one another, permit adjacent strips to pivot relative to one another. This is of decided advantage, particularly where inside window installation is to be had. For it often happensl for various reasons that the walls of a window opening are not truly rectangular and are slightly ot line. Now, were frame 12 of rigid construction, the walls of the window opening would require shaving until a true tit expense of time, labor' and money. But, where the frame 12 is pivotable or swingabler as here, it is clear that the sides of the frame may be swung to tit the window opening, and then securely fastened in place to the window stops.

The rubber lining previously mentioned has' further advantages'. sash members therein against sudden shocksv andv jars. It further prevents any distortion that" might occur in' the windowv framing from extending to the casing orto the sash members.

While an embodiment of' thev invention has been illus-V tratedand described in detail; it is to be expressly understood that the invention is not limited thereto;

construed to be Within the spirit of' 4` the invention and the scope of the appended? claim'.

What is claimed is:

An auxiliary Window unitv formed to` t in' window' openings' of varying sizes and to be mounted to conven tional stops about the inner walls of the window opening, comprising av rectangular casingA adapted tos receive sash members therein, a pair ofperimetrical closely spaced anges extending integrally from thel outer walls` of the casing andV dening between them a continuous narrow channel' about the casing, resilient material lining the It serves to cushion the casing and the And: it i's rnyintent toclaim the invention not only as shown and describedl but also in allg suchy forms as'may be reasonablyI inner Walls ofthe channel, four broad flat strips defining a rectangular outer frame for the casing, two of the strips being in opposed relation and having their marginal end portions recessed' in from their inner edges, the other two strips having oiset marginal end portions overlapping the aforementioned recessed marginal end portions, each strip normally extending part way into the channel between the resilient lining and being frictionally gripped by the latter, and each strip being moveable as desired further in" or out of the channel whereby the overall projected dimensions of the combined casing and outer frame may beselectively'expanded or contracted so as to t in a selected Window opening, and the outer frame being adapted to be ixed to the conventional' stops of the selected window opening, whereby the casing attains a floating relation to the fixed outer frame by virtue of the resiliently lined channel in which the outer frame is gripped.
